Does Chemo-Radiotherapy Improve Survival Outcomes vs. Radiotherapy Alone for High-Grade cT1 Urothelial Carcinoma of the Bladder?	BACKGROUND: Non-muscle invasive bladder cancer (non-MIBC) that is high-grade and confined to the lamina propria (HGT1) often has an aggressive clinical course. Currently, there is limited data on the comparative effectiveness of RT vs. CRT for HGT1 non-MIBC. We hypothesized that CRT would be associated with improved overall survival (OS) vs. RT in HGT1 bladder cancer. METHODS: Patients diagnosed with HGT1 non-MIBC, and treated with transurethral resection of bladder tumor followed by either treatment with RT alone or CRT, were identified in the National Cancer Database. Inverse probability of treatment weighting (IPTW) was employed and weight-adjusted multivariable analysis (MVA) using Cox regression modeling was used to compare overall survival (OS) hazard ratios. OS was the primary endpoint, and was estimated using the Kaplan-Meier method and log-rank tests. RESULTS: A total of 259 patients with HGT1 UC were treated with: (i) RT alone (n = 123) or (ii) CRT (n = 136). Propensity-weighted MVA showed that combined modality treatment with CRT was associated with improved OS relative to radiation alone (Hazard Ratio [HR]: 0.62, 95% Confidence Interval (95% CI): 0.44-0.88, P = .007). Four-year OS for the CRT vs. RT alone was 36% and 19%, respectively (log-rank P <.008). CONCLUSION: For patients with HGT1 bladder cancer, concurrent CRT was associated with improved OS compared with radiation alone in a retrospective cohort. These results are hypothesis-generating. The NRG is currently developing a phase II randomized clinical trial comparing CRT to other novel, bladder preservation strategies.	bladder
Prospective evaluation of return to work, health-related quality of life and psychosocial distress after radical cystectomy: 1-year follow-up in 230 employed German bladder cancer patients.	PURPOSE: To evaluate return to work (RTW), health-related quality of life (HRQoL) and psychosocial distress (PD) after radical cystectomy (RC) and creation of an ileal conduit (IC) or an orthotopic ileal neobladder (NB) for bladder cancer. METHODS: The study relied on prospectively collected data for 842 patients, who underwent 3 weeks of inpatient rehabilitation (IR) after surgery between April 2018 and December 2019. HRQoL (EORTC QLQ-C30) and PD (Questionnaire on Stress in Cancer Patients [QSC-R10]) were evaluated at the beginning (T1) and end (T2) of IR as well as both 6 (T3) and 12 months after surgery (T4). Regression analyses were performed to identify predictors of HRQoL and RTW, respectively. RESULTS: Two hundred thirty patients (IC n = 51, NB n = 179) were employed before surgery (27.3%). HRQoL improved steadily, while high PD was present in 51.0% of patients at T4. RTW rate was 86.8 and 80.6% at T3 and T4, respectively. Linear regression analysis identified RTW as the only predictor for better HRQoL at T4 (OR [odds ratio] 12.823, 95% CI [confidence interval] 2.927-22.720, p = 0.012). Multivariate regression analysis identified age ≤ 59 years (OR 7.842; 95% CI 2.495-24.645; p < 0.001) as an independent positive predictor and lymph node metastasis (OR 0.220; 95% CI 0.054-0.893; p = 0.034) as an independent negative predictor of RTW at T4. CONCLUSION: Global HRQoL improved steadily during the follow-up and RTW rates are high. However, patients often reported high PD, reflecting a need for additional psychosocial support within aftercare.	bladder
Exploring potential targets of HPV&BC based on network pharmacology and urine proteomics.	BACKGROUND: Bladder cancer (BC) caused by Human papillomavirus (HPV) infection remains a complex public health problem in developing countries. Although the HPV vaccine effectively prevents HPV infection, it does not benefit patients with BC who already have HPV. METHODS: Firstly, the differential genes of HPV-related BC patients were screened by transcriptomics, and then the prognostic and clinical characteristics of the differential genes were analyzed to screen out the valuable protein signatures. Furthermore, the compound components and targets of Astragali Radix (AR) were analyzed by network pharmacology, and the intersection targets of drug components and HPV_BC were screened out for pathway analysis. In addition, the binding ability of the compound to the Astragali-HPV_BC target was verified by molecular docking and virtual simulation. Finally, to identify potential targets in BC patients through urine proteomics and in vitro experiments. RESULTS: Eleven HPV_BC-related protein signatures were screened out, among which high expression of EGFR, CTNNB1, MYC, GSTM1, MMP9, CXCR4, NOTCH1, JUN, CXCL12, and KRT14 had a poor prognosis, while low expression of CASP3 had a poor prognosis. In the analysis of clinical characteristics, it was found that high-risk scores, EGFR, MMP9, CXCR4, JUN, and CXCL12 tended to have higher T stage, pathological stage, and grade. Pharmacological and molecular docking analysis identified a natural component of AR (Quercetin) and it corresponding core targets (EGFR). The OB of the natural component was 46.43, and the DL was 0.28, respectively. In addition, EGFR-Quercetin has high affinity. Urine proteomics and RT-PCR showed that EGFR was expressed explicitly in BC patients. Mechanism analysis revealed that AR component targets might affect HPV_BC patients through Proteoglycans in the cancer pathway. CONCLUSION: AR can target EGFR through its active component (Quercetin), and has a therapeutic effect on HPV_BC patients.	bladder
EV-301 long-term outcomes: 24-month findings from the phase III trial of enfortumab vedotin versus chemotherapy in patients with previously treated advanced urothelial carcinoma.	INTRODUCTION: This exploratory analysis evaluated efficacy and safety data for enfortumab vedotin versus chemotherapy over a median follow-up of ∼2 years from EV-301. MATERIALS AND METHODS: Patients with locally advanced/metastatic urothelial carcinoma with prior platinum-containing chemotherapy and disease progression during/after programmed cell death protein 1/ligand 1 inhibitor treatment were randomized to enfortumab vedotin or chemotherapy (docetaxel, paclitaxel, vinflunine). Endpoints were overall survival (primary), progression-free survival (PFS), objective response, and safety. RESULTS: In total, 608 patients were included (enfortumab vedotin, n = 301; chemotherapy, n = 307). With a median follow-up of 23.75 months, 444 deaths had occurred (enfortumab vedotin, n = 207; chemotherapy, n = 237). Risk of death was reduced by 30% with enfortumab vedotin versus chemotherapy [hazard ratio (HR) 0.70 (95% confidence interval [CI] 0.58-0.85); one-sided, log-rank P = 0.00015]; PFS improved with enfortumab vedotin [HR 0.63 (95% CI 0.53-0.76); one-sided, log-rank P < 0.00001]. Treatment-related adverse event rates were 93.9% for enfortumab vedotin and 91.8% for chemotherapy; grade ≥ 3 event rates were 52.4% and 50.5%, respectively. Grade ≥ 3 treatment-related decreased neutrophil count (14.1% versus 6.1%), decreased white blood cell count (7.2% versus 1.4%), and anemia (7.9% versus 2.7%) were more common with chemotherapy versus enfortumab vedotin; maculopapular rash (7.4% versus 0%), fatigue (6.8% versus 4.5%), and peripheral sensory neuropathy (5.1% versus 2.1%) were more common with enfortumab vedotin. Of special interest adverse events, treatment-related skin reactions occurred in 47.3% of patients receiving enfortumab vedotin and 15.8% of patients receiving chemotherapy; peripheral neuropathy occurred in 48.0% versus 31.6%, respectively, and hyperglycemia in 6.8% versus 0.3%. CONCLUSIONS: After a median follow-up of ∼2 years, enfortumab vedotin maintained clinically meaningful overall survival benefit versus chemotherapy, consistent with findings from the EV-301 primary analysis; PFS and overall response benefit remained consistent. Adverse events were manageable; no new safety signals were observed.	bladder
Avelumab First-Line Maintenance Therapy: Managing Patients With Advanced Urothelial Carcinoma.	BACKGROUND: The phase 3 of JAVELIN Bladder 100 trial demonstrated that avelumab first-line (1L) maintenance in addition to best supportive care significantly prolonged overall survival compared to best supportive care alone. It is now the standard of care for platinum-eligible patients with locally advanced or metastatic urothelial carcinoma that has not progressed with 1L platinum-containing chemotherapy. OBJECTIVES: This article provides considerations for oncology nurses to effectively implement avelumab 1L maintenance treatment in the clinical setting. METHODS: This article reviews clinical evidence and implications for oncology nurses caring for patients receiving avelumab 1L maintenance treatment. FINDINGS: Oncology nurses can provide comprehensive care for patients with advanced urothelial carcinoma and ensure the safe and appropriate use of avelumab 1L maintenance treatment by educating patients and caregivers, ensuring correct administration, and promptly recognizing and managing immune-related adverse events.	bladder
Perioperative, renal function and oncological outcomes of robot-assisted radical nephroureterectomy for patients with upper tract urothelial carcinoma.	PURPOSE: To report perioperative, renal function and oncological outcomes of robot-assisted radical nephroureterectomy (RNU) for patients with upper tract urothelial carcinoma (UTUC). METHODS: This was a retrospective single-arm monocentric study including all consecutive UTUC patients treated with robot-assisted RNU at our institution between 2014 and 2022. Descriptive statistics with median and interquartile range (IQR) for continuous variables and numbers with frequencies for categorical variables were used to report perioperative and renal function outcomes while Kaplan-Meier curves were computed to present extravesical and intravesical recurrence-free survival(RFS) as well as cancer-specific (CSS) and overall survival (OS) with the corresponding 95% confidence intervals(CIs). RESULTS: Overall, 70 patients with a median age of 69.6 [63.3-74.9] years were included in our study. With regards to perioperative outcomes, the median operative time was 157 [130-182] min with a median blood loss of 200 [100-300] cc. Intraoperative complications occurred in 4 (5.7%) patients but no conversion to open or laparoscopic surgery was required. Postoperative complications occurred in 9 (12.9%) patients, including 5 (7.1%) with grade ≥ 3 complications according to the Clavien-Dindo classification. The median length of stay was 4 [3-6] days. With regards to renal function outcomes, the median postoperative loss in estimated glomerular filtration rate at discharge was 16 [10.25-26] mL/min/1.73 m(2). With regards to oncological outcomes, the 3-year extravesical and intravesical RFS, CSS and OS rates were 73.6 [62.8-86.2]%, 68.1 [54.6-85]%, 82.5 [72-94.4]% and 75.3 [63.4-89.5]%, respectively. CONCLUSION: We report favorable perioperative and oncological outcomes with expected decrease in renal function after robot-assisted RNU for patients with UTUC.	bladder
A preliminary study on the establishment of a cyst and cystic neoplasm tissue-mimicking model.	CONTEXT: The present experimental models of cystic diseases are not adequate and require further investigation. AIM: In this study, a new way of producing a tissue-mimicking model of cysts and cystic neoplasms was evaluated. SETTINGS AND DESIGN: To simulate cysts and cystic neoplasms, ex vivo rabbit normal bladders and VX2-implanted tumor bladders were produced, fixed, and embedded in agarose gel. METHODS AND MATERIALS: The samples were classified into four groups based on tumor features and the maximal transverse diameter of the rabbit bladder, which were assessed using computer tomography (CT) imaging and statistically analyzed. STATISTICAL ANALYSIS USED: Statistical analysis was performed using Statistical Package for the Social Sciences (SPSS) software. The t-test was used for analyzing enumeration data. RESULTS: Twenty-one rabbit bladders (21/24) were successfully removed and prepped for this experiment, comprising eleven normal bladders (11/24) and ten implanted with VX2 tumors (10/24). The gelling ingredient used to form the visualization and fixation matrix was agarose at a concentration of 4 g/200 mL. The temperature of the agarose solution was kept constant at 40-45°C, which is the optimal temperature range for ex vivo normal bladder and implanted VX2 tumor bladder insertion. The average time required to embed and fix the bladders in agarose gel was 45.0 ± 5.2 minutes per instance. The gel-fixing matrix's strength and light transmittance were enough for building the models. CONCLUSION: We created an experimental tissue-mimicking model of cysts and cystic neoplasms with stable physicochemical features, a safe manufacturing method, and high repeatability. These models may be used to assist with cystic lesion diagnosis and treatment techniques.	bladder
Development and validation of a predictive model for the diagnosis of bladder tumors using narrow band imaging.	PURPOSE: At present, the prediction of bladder tumor nature during cystoscopy is partially dependent on the clinician's own experience. Subjective factors may lead to excessive biopsy or delayed treatment. The purpose of our study is to establish a reliable model for predicting the nature of bladder tumors using narrow band imaging. METHODS: From November 2021 to November 2022, the clinical data of 231 patients who required a cystoscopy were prospectively collected at our center. Cystoscopy was performed in 219 eligible patients, in which both tumor and vascular morphology characteristics were recorded. Pathological results were used as the diagnostic standard. A logistic regression analysis was used to screen out factors related to tumor pathology. Bootstrap resampling was used for internal validation. A total of 71 patients from four other centers served as an external validation cohort. RESULTS: The following diagnostic factors were identified: tumor morphology (cauliflower-like or algae-like lesions), vascular morphology (dotted or circumferential vessels), tumor boundary (clear or unclear), and patients' symptoms (gross hematuria) and were included in the prediction model. The internal validation results showed that the area under the curve was 0.94 (95% CI 0.92-0.97), and the P value from the goodness-of-fit test was 0.97. After external validation, the results showed the area under the curve was 0.89 (95% CI 0.82-0.97) and the P value of the goodness-of-fit test was 0.24. CONCLUSION: A diagnostic prediction nomogram was established for bladder cancer. The verification results showed that the prediction model has good prediction performance.	bladder
Correlation between androgen and estrogen receptor expression and clinicopathologic features in carcinoma urinary bladder.	INTRODUCTION: The molecular mapping of cancers by the Cancer Genome Atlas Project has accelerated the quest for new therapeutic targets for urinary bladder cancer, including sex steroid receptors. Previous studies have demonstrated conflicting results on their relationship with bladder cancer, and there is sparse data on their expression in the Indian population. The aim of our study is to examine the expression of androgen receptors (AR) and estrogen receptors (ERα and ERβ) in patients with bladder cancer and their correlation with clinicopathologic features. MATERIALS AND METHODS: In this retrospective cohort study, a total of 132 patients, who were surgically managed for urinary bladder mass by transurethral resection or radical cystectomy in our institute, with transitional cell carcinoma on histopathology and with at least two years of follow-up were included. Their demographic and treatment details were obtained, histopathology blocks were retrieved and immunohistochemical staining for androgen and estrogen receptors was performed. Then, the relationship between their expression and clinicopathologic features was studied. RESULTS: A total of 3.79% of patients showed estrogen receptor alpha positivity, 51.52% estrogen receptor beta positivity and 63.64% androgen receptor positivity. No statistically significant correlation was found between age of patients (p = 0.75/0.52/0.87), tumour stage and grade (0.71/0.3/0.21), pathological variant (p = 1/0.58/0.38) and overall survival (p = 0.70/0.052/0.45 for NMIBC and p = 0.82/0.36/0.22) and estrogen receptor alpha, estrogen receptor beta and androgen receptor-positive status, respectively. Estrogen receptor beta positivity was significantly higher in patients with unifocal (p = 0.015) and small tumours (< 5 cm) (p = 0.03), and its expression was associated with better disease-free survival (DFS) (p = 0.046) in patients of non-muscle invasive bladder cancer (NMIBC). CONCLUSION: Our study has the largest sample size conducted on Indian population with results differing from previous studies conducted on western population. Estrogen receptor beta expression was significantly associated with small unifocal tumours and better DFS. Estrogen receptor alpha and androgen receptor expression were not found to be associated with the clinicopathologic features of the study population.	bladder
The importance of second-look ureteroscopy implementation in the conservative management of upper tract urothelial carcinoma.	"PURPOSE: The purpose of the study was to evaluate the effect of second-look ureteroscopy (SU) in the endoscopic operative work-up of patients with upper tract urothelial carcinoma (UTUC). MATERIALS AND METHODS: Patients with UTUC who underwent SU between 2016 and 2021 were included. Cancer detection rate (CDR) at SU was defined as endoscopic visualization of tumor. The effect of SU on recurrence-free survival (RFS), radical nephroureterectomy-free survival (RNU-FS), bladder cancer-free survival (BC-FS), and cancer-specific survival (CSS) was estimated using the Kaplan-Meier method. Multivariate logistic regression analysis (MLR) assessed predictors of negative SU. Finally, we evaluated the effect of SU timing on oncological outcomes, classifying SUs as ""early"" (≤ 8 weeks) and ""late"" (> 8 weeks). RESULTS: Overall, 85 patients underwent SU. The CDR at SU was 44.7%. After a median follow-up was 35 (IQR: 15-56) months, patients with positive SU had a higher rate of UTUC recurrence (47.4% vs 19.1%, p = 0.01) and were more frequently radically treated (34.2% vs 8.5%, p = 0.007). Patients with high-grade disease (hazard ratio [HR]: 3.14, 95% CI 1.18-8.31; p = 0.02) had a higher risk of UTUC recurrence, while high-grade tumor (HR: 3.87, 95%CI 1.08-13.77; p = 0.04) and positive SU (HR: 4.56, 95%CI 1.05-22.81; p = 0.04) were both predictors of RNU. Low-grade tumors [odds ratio (OR): 5.26, 95%CI 1.81-17.07, p = 0.003] and tumor dimension < 20 mm (OR: 5.69, 95%CI 1.48-28.31, p = 0.01) were predictors of negative SU. Finally, no significant difference emerged regarding UTUC recurrence, RNU, BC-FS, and CSM between early vs. late SUs (all p > 0.05). CONCLUSIONS: SU may help in identifying patients with UTUC experiencing an early recurrence after conservative treatment. Patients with low-grade and small tumors are those in which SU could be safely postponed after 8 weeks."	bladder
Pharmacotherapy developments in autophagy inhibitors for bladder cancer.	INTRODUCTION: Autophagy is an intracellular process that plays a key role in the cellular homeostasis. Recently, it has been described as a potential therapeutic target in oncology, whether by activating or inhibiting its different cascades. Autophagy inhibitors interact with different molecular processes of the hallmarks of cancer. AREAS COVERED: Multiple proteins of the autophagy cascade could be aimed by specific inhibitors in many tumors, notably bladder cancer. In fact, bladder cancer has been increasing in prevalence over the last decade, and resistance to conventional treatment has been extensively reported in the literature. Autophagy inhibitors in bladder cancer have been described in preclinical studies to increase the sensitivity of the tumor to chemotherapy and radiotherapy. This paper is a review of the literature, which selected randomized trials, cohort studies, and case-control studies documenting the relationship between autophagy inhibitors and bladder cancer treatment. EXPERT OPINION: Autophagy is a promising pathway for cancer cell targeting that opens the horizons for a potential new therapeutic area in particular the multidisciplinary management of bladder cancer.	bladder
A novel cuproptosis pattern and tumor immune microenvironment characterization in urothelial carcinoma of the bladder.	BACKGROUND: Urothelial carcinoma of the bladder (UCB) is the most prevalent malignant tumor of the urinary system worldwide, which has a significant recurrence rate despite multiple treatment options available. As a unique and novel copper-dependent programmed cell death mechanism, the comprehensive impact of cuproptosis on the tumor immune microenvironment, clinicopathological characteristics and the prognosis of patients remains largely unclear. METHODS: A total of 568 UCB samples were thoroughly examined for cuproptosis patterns using data downloaded from TCGA and GEO, based on 10 cuproptosis-related genes reported previously. Then, the univariate COX regression analysis was performed on the genes that differed across the various patterns. To measure individual cuproptosis pattern, a cuproptosis score system was constructed using a principal component analysis algorithm. To validate the scoring system, immunohistochemical staining was performed on tumor tissues with different pathological grades, and experiments in vitro were conducted about the differentially expressed genes related to prognosis. Finally, the capacity of scoring system to predict the response to immunotherapy was verified by using data from IMvigor 210 cohort. RESULTS: Four unique cuproptosis clusters and two gene clusters were finally found by the investigation. The clinical features and prognosis of patients, as well as the mRNA transcriptome, pathway enrichment, and immune cell infiltration in TME, varied dramatically between various cuproptosis clusters and gene clusters. To identify individual cuproptosis patterns in UCB patients, we also established a cuproptosis scoring system. After validation with multiple methods, it was indicated that the score system could predict the prognosis of UCB patients and was significantly connected to clinical features such TNM category, tumor grade, molecular type and ultimate survival status. The clinical outcomes of UCB patients were predicted effectively according to the tumor mutation burden in conjunction with the scoring system. Furthermore, we found that the cuproptosis score had a significant correlation with the response to immunotherapy and the sensitivity to chemotherapy. CONCLUSION: This study revealed the potential impact of cuproptosis on the UCB tumor immune microenvironment and clinical pathological characteristics. The cuproptosis score system could effectively predict the prognosis of patients and the response to chemotherapy and immunotherapy.	bladder
